Registration colour name change

It's possible that the Chinese name of [Registration] mismatching with your computer's language is a problem, but it could be something else.

In my experience when I'm concerned about a possible file corruption I'd copy the contents out into another file. (Helps to choose "Paste Remembers Layers" in the Layers palette menu.) If the new file is still glitchy, then something you copied was the problem.

this script will rename the second swatch to "[Registration]"

activeDocument.swatches[1].name = "[Registration]";
